SPRINGWHEEL. p

T0 all whom it may concern Be it known that I, VILLIAM B..L EFLER, a citizen of the United States,residing at Springfield, in the county of` Sarpy and j State of Nebraska, have invented a new and useful Spring-Wheel; and I do hereby declare the following to bea full, clear, and

exact description of the invention, suchi as.;.` will enable others skilled in the art to which it appertains to make and use the same.` p

This invention relates to an improved resilient wheel, and an object in view is the provision of an inner hub rim havingfour flat springs, to yieldably support the `hub proper, said hub rim having spoke connections with a second rim adjacent the `tire or felly rim, between which felly rim and the second rim series of flat springs are in-` terposed, there being means to hold the second rim in engagement `with the series of springs and similar means `carried by the aforementioned springs to hold the hub in place.

In practical fields the details of construction may be subjected to alterations falling` within the scope of what is claimed.`

The invention comprises further features and combinations of parts as hereinafter set forth, shown in the drawings and claimed.

In the drawings, Figure 1 is a View, partly in elevation, and showing `parts broken away, `showingthe features of construction of the wheel. Fig..2 is a sectional view on line 2+? `of Fig.` l. Fig.` 3 is a detail view l of one of the flat springs and its connections with the second rim adjacent the felly rim.

Referring to the drawings, `1 designates 'the hub proper having `an annular flange 2 of considerable thickness. Surroundingthe hub proper is a hub rim 3 and spaced apart from the annular flange. Upon-the hub rim are U-shapedfmembers l having cylindrical portions Flat springs G areuprovided, one end of each of which is coiled about the cylindrical portion 5 of each U-.shapedmemi bei' 5, and arranged as shownin the draw ings, so that the peripheral edge of the flange 2 will `engage said springs, thereby yieldably mounting the hub member propel'. The U-shaped members 5 are carried by the hub rim 8. The opposite edges of the springs 6 are providedwith lugs 7 to engage the angular recesses 8 zof the flange 2, so as to hold the flange in position relative to the said springs. These recesses are large enough to permit movement of the hub mem` Specification of Letters-liatent; p Pfaftgnted N0V 24,1914 i Application led Junerl, 1914. Serial No. 842,240.

hub,` are bolted upon oppositeisides `of the` rim 3, as shown at 12, thereby holding the foregoing parts properly `inwplace. Radiatf i `ingfrom the rim 3 are the usual spokes 13,

which connect to a second rim lll, whichengage the flat springs 15. is provided, which may either have afiat surface, or a convex surface, or maybe es A felly rim 1G grooved,to receive the usual form of tire,

as shown. .Upon the inner circumference of the .felly rim `are the U-sliaped members `18 havingcylindrical portions 19, aboutwhich the ends of said `springs `15 are coiled, as illustrated.` Eachspring 15 has a free end slidably engaging `the inner circumference of the felly rim, so as to permit the spring to easily yield incident to the movement of the rim 14. Staples 20 are carried by the;

to hold them in place relative to saidlrimlil.` Annular ring plates 21 are bolted to the` op` positc sides or faces of the rim let, as shown` at These plates constitute means to hold the rim 141-, as well as the foregoing attending parts, properly in` position relative to rim 14, and arch over the springs 15, so as the felly rim, and also act to withstand all lateral strains, and maintain the wheel stable and mobile.`

The invention having been set forth, what is claimed` as new and useful. is l 1.
